this being in the "Academic & Campus Talk" section, i would assume that you meant "college".
to be honest, hindi ito tip. there are no shortcuts. complete the requirements for each course/subject to the required standard. iwasan 'yung mga late submission ng kahit ano. at lalo na 'yung di pagsa-submit ng kahit ano. sa tingin ko rin, the most basic thing you can do is to turn up. iwasan ang cutting classes at bulakbol - tsaka na 'yan pag nakatapos ka na. intindihin rin s'yempre ang lecture. yes, may google/ai/etc. pero di pupwedeng mag-search ka lang ng mag-search.
good luck sa 'yo!
